“…Restoration methods such as passive restoration (i.e., removing domestic grazers) and active restoration (i.e., replanting target plant) have been widely used in degraded sandy grasslands [4][5][6][7]. Recently, some ecologists have documented that passive restoration of degraded lands should be considered first because passive restoration relies on the natural succession of a regressive ecosystem to drive recovery without anthropogenic help, which has also excluded the disturbance of domestic animals (i.e., cattle, sheep) [8][9][10]; thus, the cost is much cheaper than the active method.…”

Soil Seed Bank and Plant Community Development in Passive Restoration of Degraded Sandy Grasslands

et al. 2016

Abstract:To evaluate the efficacy of passive restoration on soil seed bank and vegetation recovery, we measured the species composition and density of the soil seed bank, as well as the species composition, density, coverage, and height of the extant vegetation in sites passively restored for 0, 4, 7, and 12 years (S0, S4, S7, and S12) in a degraded grassland in desert land. Compared with S0, three more species in the soil seed bank at depths of 0-30 cm and one more plant species in the community was detected in S12. Seed density within the topsoil (0-5 cm) was five times higher in S12 than that in S0. Plant densities in S7 and S12 were triple and quadruple than that in S0. Plant coverage was increased by 1.5 times (S4), double (S7), and triple (S12) compared with S0. Sørensen's index of similarity in species composition between the soil seed bank and the plant community were high (0.43-0.63), but it was lower in short-term restoration sites (S4 and S7) than that in no and long-term restoration sites (S0 and S12). The soil seed bank recovered more slowly than the plant community under passive restoration. Passive restoration is a useful method to recover the soil seed bank and vegetation in degraded grasslands.

“…Therefore, eradication programmes to re-establish the original vegetation might provoke severe local extinction of endemic species [127,154], population bottlenecks, and cascading effects across trophic levels [126,155], as well as on pollinator communities [150]. Some exotic species can contribute to achieve native species conservation policies [133]; sometimes, even the employment of exotic species has been proposed as an effective action for ecological restoration [156,157].…”

Exotic Plant Species in the Mediterranean Biome: A Reflection of Cultural and Historical Relationships

Mediterranean Identities - Environment, Society, Culture

The Mediterranean basin was the world's cradle of agriculture and the first human civilisation. In the Neolithic age, the agrarian culture expanded throughout the Mediterranean basin from the East to the West. Later, an expansion of agrarian culture and trade occurred, associated with the European colonialism, giving rise to a great plant exchange among Mediterranean-type regions. Despite being a biodiversity hotspot, the Mediterranean biome has been subjected to several anthropic impacts, such as alteration of land-use and cross-introductions of exotic species. The millenary anthropic modification of the landscape occurred in the Mediterranean basin gave rise to the formation of seminatural systems in which plants co-evolved with anthropogenic activities over a long time. Thus, species that originated in the Mediterranean basin might have developed a key role in other agro-silvo-pastoral systems along the whole Mediterranean biome. Research is biased towards highlighting the negative impact of exotic species on the ecosystems. To defy the traditional belief, outstanding recent literature focused on the positive effects of exotics on native communities was reviewed. Exotic species seem to have a key role in Mediterranean-type seminatural systems, as evidences of tolerance and facilitation processes were found. Exotic species that have co-evolved with human practices over millennia seem to enhance biodiversity in the Mediterranean biome.

“…Many authors have mentioned the capacity of rejuvenated vegetation to effect improvements in the physicochemical and biological properties of the soil; examples can be found in articles by Parrotta (1992), Grubb (1995), Montagnini (2000), Kobayashi (2004), Macedo et al (2008), and Jeddi and Chaieb (2012).…”

“…Proof of the potential of revegetation with either native or exotic species to facilitate the development of land coverage by vegetation can be found in various studies, such as those by Kuusipalo et al (1995), Guariguata, Rheingans and Montagnini (1995), Haggar, Wightman and Fisher (1997), Lugo (1997), Parrotta, Turnbull and Jones (1997), Powers, Haggar and Fisher (1997), Keenan et al (1997), Keenan et al (1999), Ashton et al (2001), Carnevale and Montagnini (2002), and Jeddi and Chaieb (2012). Newsham, Fitter and Watkinson (1995), Guerrero, Rivillas and Rivera (1996), and Alguacil et al (2011) have pointed out the importance of heterogeneity within the diversity of the plant species utilized in a revegetation program in order that ES related to the facilitation of the development of land coverage by plants are promoted.…”

“…McNamara et al (2006) have further highlighted that RDA techniques which associate the employment of exotic commercial species with the development of native vegetation are in addition capable of promoting ES related to water conservation, biodiversity, soil conditions, and natural resources in general. Jeddi and Chaieb (2012) have identified ES related to the improvement of biodiversity, of soil conditions, and of the development of plant cover resulting from revegetation with the species Acacia salicina. Table 2 also presents the ES which were identified in these studies.…”

Environmental Services Associated With the Reclamation of Areas Degraded by Mining: Potential for Payments for Environmental Services

et al. 2016

View full text Add to dashboard Cite

This paper discusses the potential of associating environmental services (ES) with techniques for reclaiming degraded areas (RDA) used in the mining sector, considering the current trends in payments for environmental services (PES) in Brazil. A literature review with content analysis generated results which identified the ES generated for eight cases of RDA in mining. As an example, ES related to soil enhancement were found. A more extended review of general RDA techniques confirmed the potential for associating other ES to RDA techniques used in mining, an example here is the enhancement of carbon stocks. Support for actions could come from existing PES schemes, particularly for cases where the ES identified as associated with an RDA technique are related to soil and water conservation. Concluding remarks indicate that there is a potential scenario for ES diversification in the reclamation stage of mining operations. A first step towards accomplishing this diversification envisages the creation of a PES scheme specific to the mining sector. Further studies are needed to develop criteria for fostering a PES scheme specifically for the reclamation phase of mining operations in Brazil.
